The third bath: it removes bleach residues and their reaction products, which would otherwise stain the finished slide yellow. A short step, but not one to skip.

Why it is needed

After bleaching, compounds remain in the emulsion that give a persistent overall yellow stain during second development. The clearing bath reduces them to a soluble form and the wash carries them away. The slide comes out neutral instead of veiled in yellow.

What it looks like

The step takes a minute or two and has a distinct smell. This solution exhausts faster than the others in the process, which is why it is sold separately as well as in the kit.
